What Wiki is that?

As far as I can tell jbaum81 is referring to this website ( http://wilsonminesco.com/6502primer/ )
It isn't exactly a wiki but it does contain a lot of reference material that I have come to expect out of a wikis.

I think I follow, but what have you gained by first splitting the upper 32k out? If we acknowledge that a1-14 still have to be evaluated?
The latches I've chosen require OE to be off when latching, the logic I came up with there was AND the clock pulse with write and the logic that addresses the chip then invert OE as I bring the cp high. Not in that exact order of course, I do bring OE high well before CP going high. I attached my diagram above if your interested.

I'd definitely prefer to just tie it to ground though if the output will literally just echo the state of the flipflops as they change. Here is the datasheet for the latch I chose.

Anyone have a better idea for boot?

So question. Not against people learning, but why are you attempting to clone a product we haven’t released yet?

Apologies, I was actually referencing the programming guide on GitHub, sorry for the confusion.

Replace the '574 with '273, and use its built-in clear function.
Be careful mixing logic families. 'AC11032 VIH is not compatible with 'F521 VOH.
You can replace all of the jelly bean logic used to generate both bank register clocks with a single '138, similar to BruceMcF's comment above.

are you referencing the differences between TTL and CMOS? Can you clarify or point me in the right direction as to what makes them incompatible?
